Analytic Standard Errors for Latent Gaussian Discrete-Valued Multivariate Time Series

Christopher M. Crawford, Marie-Christine Düker, Younghoon Kim +3

Unlike their continuous-valued counterparts, there are no universally preferred methodologies for modeling discrete-valued time series. This is especially problematic in fields suc…

The Fourth-Moment Theorem on Hilbert Spaces

Marie-Christine Düker, Pavlos Zoubouloglou

In this work, we establish conditions ensuring convergence in distribution of a sequence admitting a Wiener-Itô chaos representation to a Gaussian measure on a separable Hilbert sp…

Scaling limits for sample autocovariance operators of Hilbert space-valued linear processes

Marie-Christine Düker, Pavlos Zoubouloglou

This article considers linear processes with values in a separable Hilbert space exhibiting long-range dependence. The scaling limits for the sample autocovariance operators at dif…

Kernel Estimation for Nonlinear Dynamics

Marie-Christine Düker, Adam Waterbury

Many scientific problems involve data exhibiting both temporal and cross-sectional dependencies. While linear dependencies have been extensively studied, the theoretical analysis o…

Prior distributions for structured semi-orthogonal matrices

Michael Jauch, Marie-Christine Düker, Peter Hoff

Statistical models for multivariate data often include a semi-orthogonal matrix parameter. In many applications, there is reason to expect that the semi-orthogonal matrix parameter…

Breuer-Major Theorems for Hilbert Space-Valued Random Variables

Marie-Christine Düker, Pavlos Zoubouloglou

Let be a stationary Gaussian process with values in a separable Hilbert space , and let be a measurable map…

Testing common structure in high-dimensional factor models: change-point and two-sample procedures

Marie-Christine Düker, Vladas Pipiras

This work proposes a novel procedure to test for common structures across two high-dimensional factor models. The introduced test allows to uncover whether two factor models are dr…

High-dimensional latent Gaussian count time series: Concentration results for autocovariances and applications

Marie-Christine Düker, Robert Lund, Vladas Pipiras

This work considers stationary vector count time series models defined via deterministic functions of a latent stationary vector Gaussian series. The construction is very general a…

Local Whittle estimation of high-dimensional long-run variance and precision matrices

Changryong Baek, Marie-Christine Düker, Vladas Pipiras

This work develops non-asymptotic theory for estimation of the long-run variance matrix and its inverse, the so-called precision matrix, for high-dimensional time series under gene…

Testing Simultaneous Diagonalizability

Yuchen Xu, Marie-Christine Düker, David S. Matteson

This paper proposes novel methods to test for simultaneous diagonalization of possibly asymmetric matrices. Motivated by various applications, a two-sample test as well as a genera…

Limit theorems for multivariate long-range dependent processes

Marie-Christine Düker

This article considers multivariate linear processes whose components are either short- or long-range dependent. The functional central limit theorems for the sample mean and the s…

Limit theorems for Hilbert space-valued linear processes under long range dependence

Marie-Christine Düker

Let be a linear process with values in a separable Hilbert space given by for eac…
